Using the sun to dry food is the oldest known method of food preservation, and making nutritious and delicious dried fruit this way is easy to do. The ideal climate for sun drying has strong sunshine, with a minimum temperature of 85 degrees Fahrenheit (30 Centigrade) and low humidity. This article will tell you how to sun dry fruit without electricity or the purchase of expensive equipment.

Steps

Make a drying tray with a plastic screen or using cheesecloth stretched tightly on a frame. Crisscross string on the back of the frame and staple it in the corners to prevent the cheesecloth from sagging.
2
Harvest the fruit just before it becomes over-ripe. Select fruit that is free from blemishes.^{[1]

- Take the fruit indoors if it is raining and at night to prevent moisture from collecting on the fruit.
9
Equalize the fruit after drying to allow moisture from some pieces to transfer to the dryer pieces. This can be done by stirring the pieces for a few days or by placing them in paper bags, hanging the bags on a clothesline and shaking the bags a few times a day for a couple of days.
10
Store the dried fruit in a container with a tight-fitting lid or in a zipper-seal bag.^{[8]

You can use a food dehydrater to dry out the grapes or use the oven on a low temperature.
Question

I want to sun dry figs, what are the steps?

Community Answer

First, wash the ripe figs. Cut them in half. Lay them on a rack with plenty of holes. Cover them with a cheesecloth and secure it tightly around the rack. Place the rack under the sun and let the figs dry for 2-3 days.
Question

Can a white handkerchief be used in the absence of cheesecloth?

Community Answer

If it's thin and gauzy, maybe - the key here is that cheesecloth has a very loose weave which allows moisture and air circulation.

Warnings

Do not use screens made from galvanized metal, which can oxidize and leave a residue on the fruit.

Do not sun dry fruit where there is a lot of air pollution, as the food can be contaminated.
